There is a good chance you will receive upgrade prompts to Version 2, which is a PAID upgrade that we released earlier this year, but it is not mandatory. You can turn off the prompts by going to Preferences > General and turning off the feature that does auto-checks for updates on startup. There is a discounted upgrade offer for existing license holders.

Please be aware that we will not be releasing any more updates for Version 1, as we are focusing our development on Version 2. This means that eventually all builds of Version 1 will have problems and stop working at some point.
